Information regarding Pregnancy for Women with a History of Thyroid Cancer

Patient information A-Z

You have been treated for thyroid cancer and are now taking levothyroxine medication.

If you wish to become pregnant in the future we would advise the following:

Before you plan to become pregnant

Before you plan to become pregnant ensure your thyroid function tests are within the range recommended for you, as determined by the thyroid cancer clinic.

If you miss a period

If you miss a period, perform a pregnancy test. If this is positive and you are taking levothyroxine immediately increase your dose by taking an extra 25 micrograms of levothyroxine every day.

If you have a positive pregnancy test

If you have a positive pregnancy test, please inform the thyroid cancer specialist nurse on 01223 348796 or 01223 596182 AND make an appointment with your GP as soon as possible for a thyroid blood test. The thyroid cancer specialist nurse will review these results and let you know if any changes need to be made. Please only adjust your dose on the advice of the thyroid cancer specialist nurse or a doctor in the thyroid cancer clinic.

Further blood tests

The thyroid cancer specialist nurse will inform you regarding further blood tests during pregnancy.

Please keep this leaflet in a safe place and give a copy to your GP.
